20 People Share The Unforgivable Thing Their Siblings Did That They Can Never Forget

Published 1 year ago

The first friends we have in life are generally our siblings. While some sibling relationships may stand the test of time, others can fall apart just as easily. Although sibling rivalries are generally harmless, what about when it goes too far? A reddit user asked, “What was the most messed up thing your sibling did that you can’t forgive them for?”

Many people stepped up to answer and the following narrated incidents reveal, when a sibling went too far and our OP just could not forgive the particular transgression, either for being put at fatal risk or for having their boundaries disrespected and invalidated.

Threw a party at our house while the rest of the family had gone to a funeral out of state. Many people there were kids my age/classmates who went in my room (which was bad enough in my eyes) and stole things. I’ve never felt so violated.

Still working through this, but I cannot forgive my brother for the crime he is being charged of. I found out over social media, he never told me he was arrested and is currently in trial for these crimes. It is honestly the most f****d up s**t I ever heard of.

My brother is being charged with putting cameras in the bathroom of his place of employment.

I have been having a hard time dealing with this. I know what he did has nothing to do with me or anything I did or didn’t do. But I can’t help feeling ashamed and sorry for the pain he caused.

ETA: He has been found guilty of all charges.

As my grandmother lay unwell in her bed, from what would later turn out to be the first stages of kidney and liver failure…

He stole every single bit of cash in her handbag, over £900 we think.

She died in a delirium, screaming about how one of her grandchildren stole from her. My mother thought it was the toxins in her body.

When my parents found out they did nothing and let him keep the items he bought. This is the not the worst thing he has done in his lifetime.

I will never forget and I will never forgive.

My brother locked me out of the house when there was a tornado warning. There was blasting wind, rain, and hail, and the sirens were going. I had a full-blown panic attack.

He later laughed at me and mocked me.

Our parents came down on him like a ton of bricks and majorly punished him, but it didn’t really work.

This was just one of the many horrible things he did to me. He hated me from the day I was born because he didn’t want a sibling. Our parents would punish him but like I said, it only made him worse.

Thankfully, karma finally got him. He wrapped his car around a streetlight two weeks ago.

He can rot in the ground now for all I care.

I may make a post about this in AITA later on.

EDIT: Yes, he died.

When I confided in my older sister that my husband and I had been trying for a baby unsuccessfully for over a year, she sarcastically said yeah I would like to see you with a baby. Was probably the worst thing anyone has ever said to me.

My family was in Mexico for my step sisters wedding… It was the wedding night and we were all absolutely wasted from drinking free tequila.
After leaving the club on our resort, my step brother and I got into some sort of argument over a movie or something. (I am not sure what happened) but he has always had a temper issue.
I guess I told him I would punch him, so he came at me full speed and football tackled me but lifted me into the air over his shoulders and body slammed me onto my back.
I slammed the back of my head on the uneven rock tiled ground..
Next thing I knew I was at my hotel room about 10 minutes away and a bunch of people were in my room standing over me. My step brother was crying like crazy.
These idiots left me in my room and I slept for 12 hours. Woke up the next day with absolutely zero hearing. Panicked and ran into the shower thinking I had water in my ears. Thankfully it came back within 10 minutes…but then I noticed my temple on the left side of my head was swelling out like a basket ball..
Long story short I had an Acute Subdural Hematoma brain injury.
My brain was bleeding & swelling.
I finished the trip and flew home on a plane, all which should’ve killed me and didn’t get to a hospital until we got home to Canada. Where I was immediately put into a controlled coma state.
This happened in 2011. I haven’t worked a normal job since , I’m on disabilities. Worst of all it caused major issues years later which affected me emotionally and painfully with severe cluster migraines. It destroyed my relationship with the love of my life and mother of my child.
My whole life has been altered.

My sister phoned every new employer I had over the years and said bad stuff about me. She would invite me over to diner to find out who my boss was. Then weeks later she would invite me over and ask how it’s going at work.

My older brother once stole a bunch of my stuff to sell to a pawnshop to pay for drugs. He apologized to our parents for breaking their trust. To this day, he still refuses to apologize to me, because in his messed up logic, it was only our parents trust that was violated. This was over 10 years ago.

My brother got married in Vegas. Our small family isn’t the nicest and he was afraid my mom or her husband would make a scene. Nobody was invited. I was completely fine with it. In fact, kind of wanted to do that myself.

Then years later, it’s my wedding. What does he do? He made a scene. Tried to fight my husband right after our first dance in front of everyone.

Still love my brother, but man… that hurt.

I was born with a severe physical disability regarding my eyes (nearly blind). My big brother has always been a total a*****e about this. Sometimes I feel like he completely lacks even basic compassion and he’s honestly pretty ableist. He has said countless things that have deeply hurt me but there’s one thing in particular I will never be able to forget or forgive him for. Already as a little child, I had to go through numerous eye surgeries. As you can imagine, that was pretty tough for me. The loneliness in the hospital, being scared before the surgery, dealing with the pain post-surgery (for several months usually), having to take all sorts of meds… not the type of thing that kids usually have to go through. When I was 11, I had to undergo one of these surgeries. The whole thing was quite exhausting, both physically and emotionally. I was so happy when I was finally back home. As odd as it may sound, all I wanted was to go back to school. I wanted to be done with the pain and the constant doctor visits and just live my normal life again. During dinner I took off the protective plastic shell because the doctors at the hospital said it would help my eye to heal if some fresh air reaches it. Naturally, my eye was extremely red at the time because I had had my surgery was 1 week earlier. I usually suffer from a pretty painful inflammation post-op that needs to be treated with eye drops. Instead of consoling me or telling me how he feels bad for me, my brother (who is 5 years older) started bullying me in a very aggressive tone, saying things like: “stop looking at me with your disgusting eye” and “you look like a f*****g disgusting monster”. He got so angry at me, as though I had deliberately made my eye look this way just to bother him.

In that moment, something inside of me just kind of broke. The fact that I had to go through all of this pain and misery while my siblings were able to live a normal, happy and carefree life already felt quite s****y. As a child, I often asked myself why me. But he called me a “monster” and my eye “f*****g disgusting”… that just hurt so, so badly. I started crying and my dad told my brother to cut it out but of course by this point the damage had already been done.

It has now been over 20 years since this incident and it still hurts me so much that my own sibling would say something like that to me. In my mind, that’s different from normal sibling fights where you call each other an a*****e. It is completely impossible for my brother to empathize with my situation and that incident is still the best proof for this.


I was 18, she was 14. I was extremely ill- doped up on the daily and bedridden from what turned out to be a slowly dying organ and some undiagnosed digestive conditions. I was in a complete haze for over a year from pain and meds. I technically wasnt allowed to stand by myself or feed myself without help. I didn’t get the assistance I needed at home, and hurt myself pretty often just trying to take care of myself, but thats a different story. Point is that I was incredibly weak, underweight, enotionally fragile, and drugged to the teeth.

My sister decided she was jealous of the little attention I was getting and decided to deprive me of sleep as much as she could. Punching me awake, threatening the few things I had that kept me feeling sane, pouring paint on and ripping my things, and then gaslighting me into believing it was all drug dreams and stuff I did myself while high. No one in my family believed me when I complained, and helped my sister gaslight me into believing even if she was hurting me, she was sleepwalking and it wasn’t her fault. It only stopped after my then boyfriend heard her screaming at me from the couch downstairs where he was napping and threatened to move me out. I was moved into a different room and allowed a lock on my door as of the next day.

The whole family is dysfunctional. I don’t talk to any of them anymore.

My younger brother, being the favourite child, would often tell my mum that I abused him when she was at work just to show me he had POWER over me. I would get hit for no reason on a daily basis.

I gave him a left hook once for a seperate argument. Best gift I ever gave anyone.

Outed me in front of my homophobic family.

My brother planted drugs in my car – packaged for sale, 5 year mandatory prison sentence – and called the police saying there was a dog locked in a car in front of his house with no water or open windows. Luckily I pulled up at the same time as the cops & showed them my dog was fine, the sunroof was open & he had full bowls of food and water.

I bought a motorcycle. Before I bought it I had a lengthy discussion with my wife of in case of accident what quality of life of be willing to live with. We talked and she knew my mind. I did have a catastrophic accident. I was in a coma for 42 days. I died 3 times. Talk came about what my quality of life would be afterwards and pulling the plug. My siblings wanted me to live at all cost no matter my wishes. They tried to take my wife’s medical rights away. I have a good life, my wife made the right choices but asked me not to subject her to my family anymore. I went no contact.

My wife and I had been trying for years to have kids. Meanwhile, my Sister was Fertile Myrtle popping the first 2 out without even trying.

My wife and I conceived twins, and we were so excited. We told the family the names were were going to use, etc. We ended up losing them.

My sister doctor shopped around until she found someone that would diagnose her with Infertility and got prescribed drugs that would make it significantly more likely to have twins.

She used the names we had planned to use.

It took well over 10 years before we spoke again

I insist on forgetting this, because I want to forgive it, but it’s still pretty fresh.

I went to visit my family (I study in a different city now) and a couple days after I came back, I noticed my debit card was missing. I prefer to pay in cash so I didn’t need it until then, but naturally, I panicked.

I INSISTED, when the bank lady asked me if I had any younger relatives that could take it, that my brothers would never do such a thing. She convinced me to at least call my parents just in case, because that’s a lot more common than the card actually being stolen, and after asking once my mum told me noone came clear.

Two days later, when the police got included, my mom called. Apparently, when my little brother realized how easily he could be caught and held accountable, he confessed to taking the damn card and buying some stupid game with it.

I had to call the police and tell them. Which wasn’t easy, for someone with anxiety (it was terrible). My brother apologized, returned the card and the money, and a few months later, proceeded to ask me to buy him an expensive toy this year for his bday, as if nothing happened.

It gets me that I was SO sure. I trusted my family, why wouldn’t I? We got along. It hurts. (Aaaand now I’ll do my best to re-forget this so it stops making me sad)


when I was around 12 and my brother was 9, my mom and dad left to go up north for a day (we are in the south) My mom knowing I was responsible, Let me watch my brother for the day until they came back late that night. Problem was we had a VERY toxic relationship in between the 2 of us. a couple of hours later after the parents left(my brother being the psychopath he is with anger issues) got very offended at a stupid sibling joke i said. Instead of normally lashing out he silently went to the kitchen. I casually went to the bathroom and after I was done I came out and my brother from behind me (the bathroom was in a hall so he was at the end and i was walking away from the end) Ran up behind me with a steak knife he heated up with the fireplace outside. my mf as* turned around and ran into my room and locked the door. He was shoving the knife under the door screaming “open up!” He gave up after a while but i still locked myself in the room until my parents came back..

they came back to my brother passed out on the couch with a steak knife in his hand and me starving in my room locked upstairs terrified.

in the end, none of them believed me to this day what happened and my brother still denies it.

My brother told me I would be allowed to see my niece, under his supervision, until she was old enough to “know what you are”, at which point he would decide what, if any, involvement I would have in her life.

I’m gay and now have two nieces, the elder of which I haven’t seen in nearly 5 years and the younger I’ve never met. Even overheard a conversation while on the phone with another family member during the holidays, that the elder niece doesn’t even know she has an uncle.

Shanilou Perera

Shanilou has always loved reading and learning about the world we live in. While she enjoys fictional books and stories just as much, since childhood she was especially fascinated by encyclopaedias and strangely enough, self-help books. As a kid, she spent most of her time consuming as much knowledge as she could get her hands on and could always be found at the library. Now, she still enjoys finding out about all the amazing things that surround us in our day-to-day lives and is blessed to be able to write about them to share with the whole world as a profession.
